Ruby ActiveRecord Basics Migrations and Relationships Relationships

I am confused by the addition of the blogpost_id. What should I be looking for concept-wise in the rails docs?

OK so I tried the basic belongs to ... has many relationship:

lass BlogPost < ActiveRecord::Base has_many :comments end

class Comment < ActiveRecord::Base belongs_to :blogpost end

... "but I guess that relationship didn't work out" as far as the question was concerned. (Pun intended)

I have tried different combinations of this syntax and tried a few different variations, but apparently I am amiss somewhere. I'm sure the addition of the blogpost_id must be throwing a curve ball in this, but if it is something covered in the video, I missed it and am having a hard time finding it. Please let me know how to approach this problem. Thanks for hearing out my question :)

This is the last objective I haven't completed on this course, and I am revisiting this now having completed everything else..

models.rb 
class BlogPost < ActiveRecord::Base
end

class Comment < ActiveRecord::Base
end

Hi David Thrower! The comment about the blogpost_id is only explanatory—it doesn't need to be referenced in your code as it's handled by Rails for you.

Your challenge will pass if you add an underscore to blogpost: belongs_to :blog_post

David,

Thank you for your response. I got past this one and even completed the rails development track. I see that I had just made a typo that I was missing. .. Thanks. Feel free to collaborate in the future.
